or CHICAGO, ILLINOIS i WINDOW Application :filed April 18,

My invention relates in general to windowsv and more in particular to a Ventilating type.

of window adapted to be set into arelatively larger window such as the usual type oflarge stained glass windows commonly found in churches.

In general my present invention is animprovement on the window disclosed in Patent #957,836, issued on May 10, 1910, tov Benz t K Y vention, I provide hinge slots in the frame 'with trunnions on theV sash adapted to extend and Rossbach.

The Window shown in the patent referred to, in general has been found satisfactory and has been used extensively in church window and similar installations. It is subject to some objection, however, due to the fact that at the points where the sash is hinged to the frame, there is a small area through which daylight can be seen, itbeing impossible or impractical in ordinary commercial practice to fit the members suiiiciently tightly4 so that no space can be seen at this point between the Y sash and frame. This prevents the window from being fully weather proof under all circumstances, and notwithstanding the fact that this difficulty has beenlpresent'in this type of window for years past, no satisfac- A tory practical solution been obtained.

The principal object of my present inven- 301 tion is to improvewindows of this type.

Another Objectis to make windows of this type entirely weather-proof Satv the places where the sash is hinged to the frame.

Another object is the provision of an im-l proved pivot or hinge construction between the sash and frame.

Other objects and features 'of the invention will be apparent from a consideration of the ,following detail descriptiontalren with th accompanying drawings, wherein, 1 f

Fig. 5 is a similar View showing the frame,

Figs 6 and 7 are fragmentary perspective views of the sash and framer'espectively, constructed as a modification ,ofV the principal design'g,

According to the'main `features of the infv owing the normally to be expectedbetween the sash and y frame at thev point of pivot.V These weather` blocks lsecured to the frame andsash and disposed in a plane at right angles to the axisof the pivots also function as stops to prevent the sash` fromr being opened too great a distal-16e although other Stop meansare shown' 75 and may beused in actual practice.

Referring to Fig. 1 ofthe drawings, Ifshow a relatively large window A, inn which `my improved Ventilating window B is inset, this window B normally comprising only arela-` tively small partof the -areaof the window proper, butl being vsufliciently large to secure the necessary" ventilation. This arrangementV is customary in the art, and does not represent a feature o-f my invention but is shown for the purpose of illustrating anse to which'` the window may be put. Y y Y v Refer now first to the frame shown in Fig. 5. This comprises 'top'and 'bottom frame members 11 y and 12 and side frameinembers 13 and 14. The top frame member `has a small channel meinberl into which the glass or frame of the window above the inset win l dow may be.disposed and held byrsuitable means. It 'willvbe understood that similar framemember, but in the present instancevthe frameA member is` showngas disposed on three of itslsideswvithin, an outerfwooden frame, K constitutingthe frame'ofthe main window. 100

Veather blocks 17 and 18 are secured to the inside of the frame by suitable means.

such as screws and pivot slots 19 and 21 are provided in the longitudinal or side frame members and extend partly into the weather blocks 17 and 18. Y These slots are of somewhat bayonet character, rhaving a, depression at their ends whichV is adapted to receive the pivot or trunnion members carried by the sash, which will be described. In this form the slot extending both through the rame member and a part orn the weather block forms a lrelatively wide bearing surface for the trunnions. Looking atthe weather block 17, the top portion 17aisrelatively wide, but` the bottom portion 17 7o is of less width, anV

- angular po'rtion'170 being shown between'the Wide and narrow portions. The/block k18 is of course of thesa'me shape.

, Above the ira-me member on the outsidethereotis a combination stop `and weather nation stop andweather strip 23 is Valso pro-V vso strip 22, this stripeitending fromV as place slightly above the pivot section on each side and extending entirely around the top Yiframe member 11 (see Fig.,2). An insidecombivided, this stop extending on both sides from a point slightly belov7 the pivot section and also extending acrossthe bottom fa-me member 12. Y Y

' The sash shown in Fig. 4; has a top member 24., a bottommember '25 and side members 27 and 28. The side members carry outwardly extending pivotsV or trunnions 29 and, 31,A the `oi? the sash Vextending down on bothy sides tof a rposition slightly above the'trunnions. v'()n the outside of thersash'combination weather position being such as to cooperate with the slots 19 andr21 respectively in the frame member'. Adj acent the trunnions aresashvvveather blocks 32 and 33 secured to the sash by suitable means such asscrewsk TheseV sash blocks have;` approximately the Vsame thickness as the corresponding V and cooperating blocks on the frame and their width issuch as to fit in the space on the Viframe not occupied by the blocks 17 and 18. rlhe specilic cooperation between 'these members will bey eX- plained more fully hereinafter.

The sash Vis also provided with a top inside `Weather strip 3.4, suitably secured rto the inside of the sash, `the projecting portion of this rstrip extending entirelyaround the top and stop strips are also provided. These includel a bottom strip 36, which is substantially permanently secured iniposition'and may form a permanent part of the sash,`and

removable side stripsv 37 and 38.` These side l,strips cooperate with the strip 36 to form' a continuous strip and-they extend up to a point slightly below the trunnions 31. i f `It isfof courseunderstood that theV sash carries any suitable type of glass whichmay bea clear glass, frosted glass, or it maybe a coloredglasssuch as .used'in' churches'. In thisy or pivot, .it mustii'rst be observed that all of V*the combination, stop and weathery strips slightly overlap these blocks. rlhe combination stop and weather strips cause the window to' be tight and weather-proof at all places,

except in the vicinity of the pivots Since the weatherbloclrscarried by the sash and frameKV are removably secured to thesash and iframe.` Y

respectively,the effect is the-'same asif the sash and trame overlap each other at these points, and accordingly the windowyas a whole can be made to be thoroughly -weathen prooi?. lt is understood, or" course, that since the sash must be permitted to pivot freely,

the several combination stop and lweather strips provided cannot eXtendin anycase Yenough to interrupt they free pivoting movement of the sash. Accordingly, the weatherk yblocks carried bythe sash and frame are made to talre up the yspace betWeen'the Weatherv strips and overlap the strips to-some consider; able extent. l

l shall now describe the cooperation be'- tween the members, referring to the weather block 83 and the "weather block 17 tor convenience of description,- butk it will be'understood that the weather block 33 infact cofV operates withthe block 18, which is 'not shown Y in its entirety in `Fig. V5.

Thebloclr 33 has av vertical edge 33d facingl thetrunnion 31, and when thev ywindow is closed this lies relativelyy snuglyagainst the verticaly edge 17cZfo2t the block 1 7. When the sash is swung open this edge 33a rides around on the arcuate edge 17e'i'iiitil Vthe bottoni di agonal edge 38?) engages against theslanting edge`17c on the block 17. It will be seen from.

this arrangement that VYthese,weather blocks are in suilicientlyclose engagement at all times as tomakeasubstantiallyweather-proof joint. The narrow portion 17 Z9 permitsfalree movement of the bloclrf17y as the, sash is opened and also functions to carrythe;

Weather-proofing action of the Vblock .lV well" below the beginningv Aof the contiguous weather strips.. i'

38 must `first be removed. 'The sash istheii The sash is designed to berelatively easilyY removed 4from the frame, and thisis facili-f tate'dV by the direction ofinclinationand the construction of the slots 19 and 21.. orderv to remove the sasln'liowe'ver, the strips 37 and swung open and. pulledlV upwardly', and in.-

wardly so'that the sash moves betweenthe@` the bell crank being pivoted to the sash and having a` chain 44 secured to one arm thereof. A catch 46 carried by the trame is adapted to receive the chain and hold the window open a distance, determined by the place where the chain is secured in the catch. f

In Figs. 6 and 7 I show a modied term, which secures substantially the same results as the main framepreviously described. l In this form the sash member 138 carries a weather block 117 and a trunnion 131 forming aartot the weather block. rlhis trunnion canot course extend entirely through the member 138 to form a stronger construction.

A slot 121 is formed in the frame member and a weather block 133 secured to the trame member is adapted to cooperate with the block 117 Substantially the same type of construction and the same functions are Aperformed by these two weather blocks, including the stop teatureobtained by the use ot the diagonal edges of the two blocks, which are adapted to meet whenthe sash'is swuA g open. It will be observed, however, that in this form less bearing surface is provided for the trunnion. The usua'l combination stop and weather strips shown 1n these two gures also overlap the two inserted weather blocks disposed adjacent the point ofvpivot.

It is believed that from the foregoing description the manner of constructing and operating the invention will be clear. It is understood that certain modiiications and changes may be made without departing from the spiritand scope of the claims.

What I claim as new and desire` toprotect by Letters 1Bat-ent ot the United States is l.
